IMPROVEMENT IN REVOLVING HARROW.

To ALL WHOM IT MAY OO'NOERN:

Be it known that I, BAXTER IiYON, of Mount Pleasant, in the county ofWhitesides, and State of Illinois, have invented a new and usefulRevolving Harrow; and I do herehy declare that the following is a full,clear, andexact description of the same, referenceheing had to theannexed drawings, making part of this specification.

This invention relates to an improvement in revolving harrows, and itconsists in the arrangement of two pairs of revolving toothed wheels,yconnected together in such a manner that the rear pair follow nearly inthe path of the leading or forward pair;v and the invention consists inthe arrangement of these wheels, with refer ence to each other, so thatthe leading pair shall havean inclination outwards and downwards fromaline drawn through the centre of the holsters, which support-them inthe direction of the movement of the barrow, and so that the rear pairshall have an inclination inwards and downwards with reference to saidline.

Figure 1 is a top view of the harrow complete.

Figure 2 is a sectional view on the line a: z of fig. of the leadingpair of wheels, showing the position they assume when in use; and

Figure 3 is a sectional view ofthe rear or following pair on the sameline, showing the position which they occupy with reference to theleading pin.

Similar letters denote corresponding parts in the several iigures.

'A A are revolving toothed wheels, arranged side by side, having theaxis upon which they rotate fastened to the holster C, and so arrangedwith reference thereto as to compel-them to assume the position 4showinin iig. 2 ofthe drawings.

A A are the second pair of toothed wheels, with their axis fastened tothe holster C', and so arranged as to cause the wheels to assume theposition shown in iig. 3 ofthe drawings.

B is a reach, extending from the frontto the rear holster, for thepurpose of connecting the rear pair of wheels to the forward ones. Thisreach is fastened permanently to the bolster of the rear pair of wheels,but at'its front end, where it connects with the holster upon the frontwheels, it carries a cleviswheel, which is attached to and works withina staple secured to said holster; the object of the last-namedarrangement being to permit the harrow to be turned around the cornersof the held with facility, or to be propelled in a circle if necessary..i

C is a bolster, extending from centre to centre of the front revolvingwheels, and to which isrfastened the axis G of such wheels. p

C is the holster, carrying the axis'of the rear revolving wheels, whichis arranged in all respects like the one above described, except thatthe axes of the wheels are so arranged as to give a reverseinclinationto the revolving wheels.

D is the tongue or pole to which the animals are attached for propellingthe barrow.

E E are braces for securing the pole to the bolster, to each of which'jvthey are fastened with bolts in the usual manner. v

Gr G and G G are straps of metal fastened to the holsters, and uponwhich are made or secured the axis upon which the wheels A A and A Afrevolve. As before stated, the-axes of the leading pair of wheels are soset with reference to each other that the inner edges of therevolvingwheels, as they rotate, are considerably higher than theirouter edges, while those of the rear wheels are the reverse of thoseofthe leading ones, or are so set with reference to the bolster that theouter edges of the wheels, as they rotate, are considerably higher thantheir inner edges. l

' It will be seen from the foregoing description that, as aconsequenceof the arrangement of the two pairs of revolving wheels, I amenabled to construct a harrow which lmore thoroughly inixes andpulverizes the ground than any now in use. The above-described result.arises from the fact that after 'the first pairof wheels pass over anyone part, they have a tendency to leave the earth higher in the centreof their line of progressive motion than at the sides thereof, thusleaving it in the best possible position for the spreading action of therear Wheels consequent upon their different position upon their axis ofrotation.

Thus it will be seen that While the revolving har1ow,as usuallyconstructed, acts upon the earth only A through the rotary motion givento it by propelling it forward, mine has the additional merit of givingtwo sidewise movements to the earth, and finally leaves it in fai'better condition, so far as evenness of surface is concerned, than theordinary kind of hai-rows.

I am aware that two pairs ofrevolving wheels, the one following theother, as in my case, have before been used, and hence I do not `claimbroadly such arrangement; but

What I claim as my invention, and desire to secure by Letters Patent,is- A revolving harrow, the front and rear portions ofwhich'beingconstructed substantially asi-described, are connected to euch other byajointcd or iexible connection, as and for the purpose described.

In testimony whereof, I have signed my name to this specication in thepresence of two subscribing witnesses'.
